candela: [noun] the base unit of luminous intensity in the International System of Units that is equal to the luminous intensity in a given direction of a source which emits monochromatic radiation of frequency 540 × 1012 hertz and has a radiant intensity in that direction of ¹/₆₈₃ watt per unit solid angle.
The Candela […] is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation of frequency 540 × 1012 Hz, Kcd, to be 683 when expressed in the unit lm W–1, which is equal to cd sr W–1, or cd sr kg–1 m–2 s3, where the kilogram, meter and second are defined in terms of h, c, and ΔνCs.

The candela so defined is the base unit applicable to photopic quantities, scotopic quantities, and quantities to be defined in the mesopic domain. From 1909 until January 1, 1948, the unit of luminous intensity in the United States, as well as in France and Great Britain, was the international candle , which was maintained by a group of carbon ...
Candela C-8 Polestar Powered uses the same 69 kWh pack as the Polestar 2 electric performance fastback. Polestar batteries also bring DC charging to the table, which means C-8 now combines the longest electric range with the fastest charging times. The result is the longest-range electric boat on the market, by a factor of two.
Kandela. Kandela (značka cd, z latinského candela) je jednotka svítivosti. Je jednou ze sedmi základních jednotek soustavy SI .
Oct 13, 2014 · Candela: a Unit Used to Measure Luminous Intensity. We'll start with candela (cd) – also commonly called candlepower. Candela is the base measurement for describing luminous intensity. It describes how bright the light source is, which shows how far away from an object you can be while still being able to see it.
